Thought I'd post up if anyone is interested, as its been a while since I've seen anyone post about reducing distortion.
50x50x3mm box, tee joint, stainless steel.
3mm packer underneath the joint, clamped at both ends on a flat table.
Welding around 90-100 amps average maybe with low speed pulse.
Comes out straight every time, saves flipping the trestle once since you can weld all 4 sides in place, and saves a hydraulic straightening operation to get the tops to the right dimension.
Main problem was getting the hang of the front side weld, I couldn't get comfortable, took around 40 of these joints to get back to the same pretty look I was getting on the flat.
Post up your pre-setting techniques!
